Problems solved by technology
[0003] In the prior art, usually the two processes of bending the coil to be welded to form a cylindrical tank wall and using a welding torch to weld the two ends of the cylindrical coil to be welded are sequentially performed on the same production device. This type of production device has a complex structure and requires a lot of manual operations, which not only seriously affects the production efficiency, but also makes it difficult to ensure the welding effect of the oil storage tank

[0051] Such as Figure 6 As shown, when the first motor 11 drives the welding torch 5 to move, the push rod 21 can rotate counterclockwise under the action of the first inclined surface 56 on the push plate 55. ° and continue to rotate, under the action of the pulling force of the first spring 23 and the limiting of the first limit point 12, the second limit point 13, the third limit point 14 and the fourth limit point 15, the push rod 21 and the rocking bar 22 can rotate a certain amplitude synchronously and remain relatively stationary.
[0052] Such as Figure 7 As shown, the moving direction below the push plate 55 is the moving direction of the push plate 55. When the push plate 55 moves to the left, the push rod 21 continues to descend under the action of the first inclined surface 56 on the push plate 55. When the bar 21 descends to 180° with the rocking bar 22, the push rod 21 quickly descends for a certain distance. When the push plate 55 moves to the right, under t...

The invention discloses an oil tank rolled plate welding machine, and belongs to the technical field of tank body welding devices. The oil tank rolled plate welding machine comprises a rack, a transmission shaft, two extrusion rollers, a pressing pipe and a welding gun; the rack is provided with a first motor; the transmission shaft is arranged on the rack in an axial rotating manner, the transmission shaft is fixedly connected with a push rod, the rack is connected with a rocker, and a first spring is arranged between the push rod and the rocker for connection; rotating shafts are arranged at the eccentric positions of the two extrusion rollers, gears are arranged on the rotating shafts, and the gears are meshed with a rack; one end of the pressing pipe is connected with a pull rod, the pull rod is provided with a frame, a cam is arranged in the frame and sleeves the transmission shaft, and the pressing pipe is connected with a pressing plate; and the welding gun is driven by the first motor to move linearly. According to the oil tank rolled plate welding machine, the pressing pipe is sleeved with a to-be-welded rolled plate, the two extrusion rollers are used for rotating and extruding the to-be-welded rolled plate while the pressing pipe moves downwards, the to-be-welded rolled plate can be bent to form a cylindrical tank barrel wall, the welding gun conducts welding along a welding seam formed by the to-be-welded rolled plate, and the bending and welding procedures of the to-be-welded rolled plate are achieved.
Description
technical field [0001] The invention relates to the technical field of tank body welding devices, in particular to an oil tank coil welding machine. Background technique [0002] In the production and sales process of oil products, a large number of tanks need to be used for storage and transportation. The specific production process of oil storage tanks is as follows: 1. Bending the coil to be welded to form a cylindrical tank wall ; 2. Use a welding torch to weld the two ends of the cylindrical coil to be welded; 3. Weld the end caps at both ends of the cylindrical tank wall; 4. Grind the weld to form Storage tanks for oil products. [0003] In the prior art, usually the two processes of bending the coil to be welded to form a cylindrical tank wall and using a welding torch to weld the two ends of the cylindrical coil to be welded are sequentially performed on the same production device. However, this type of production device has a complex structure and requires a lot o...
